PICAXE 20X2 Microcontroller (20 pin)

Description:Replacement: COM-10807. We are now carrying the M2-series of PICAXE microcontrollers. This page is for reference only.

This is an enhanced PICAXE 20-pin microcontroller. The X2 series of PICAXE microcontrollers offer much more flexibility and features in comparison to the first generation PICAXEs. One of the key features of the X2 series is that almost every pin is configurable as an input or output.

PICAXE is a neat entry-level microcontroller system that is relatively cheap to get started with. The chip is programmed with a simple serial connection and the BASIC development environment is free! PICAXE has some excellent educational applications and support, and is a great entryway into more complicated embedded systems. If you’re look for a place to start with microcontrollers, PICAXE is a great way to go!

Hi, just wondering if this could be taken out of retirement – the 20M2 is newer but this one has more program space and a faster internal clock speed, and would be more suitable for other applications. I’d buy it…

Wow, despite the C.1 firmware level, I’ve made some very cool projects with this chip including a 2 axis solar tracker & Satellite chaser and another project integrating temperature, compass heading and Real Time click displaying to a serial LCD.
Has anyone interfaced a PC keyboard to this chip ?
Too bad I cannot find a simple strip line proto board for my cool projects.

Check out the 20X2 firmware. Version C.1 is what I received and it has some bugs in the ADC3 and the mask to disable hserin. Look for FW => C.2 . Version displays when the programming cable is connected and the editor is started.
